The invention relates to a method for operating a data receiver (8, 12, 13, 14, 15) for audio and/or video data, wherein a planned and variable program title sequence (23) comprising a plurality of program titles (A - H) is recorded, audio and/or video data relating to at least one program title (A - E) are received via a data link (8, 9) and are buffered, and audio and/or video data of at least one program title (A) are reproduced. The method according to the invention is characterised in that the transmission resources of the data link (8, 9) for audio and/or video data to be transmitted and to be buffered are distributed over at least two program titles (B - E) that have not yet been reproduced by the data receiver (8, 12, 13, 14, 15). The invention further relates to a data receiver (8, 12, 13, 14, 15) associated with said method and to a media reproduction system (2 - 7; 16) connected thereto, in particular in a vehicle (1).
